MILKING MACHINE.

Application filed. January 14, 1922. Serial No. 529,307.

To all 1071 am it may concern:

Be it known that l, THoMAs CUMMINGS, a citizen of the Dominion of New Zealand, residing at Waitara Road, Awakino, in the Provincial District 0t Auckland, a subject of the King of Great Britain and Ireland, have invented certain new and useful improvements in Milking Machines, oi: which the following is a specification.

This invention relates to milking machines and has for its object the provision of improved apparatus whereby milking and stripping may be performed in a' more thorough manner than heretofore without employing; the usual rubber infiations or linings in the teat cups, besides reducing the employmentoit rubber fittings and connections to a ll'llllllllllnl.

l urther objects are to provide improved means tor measuring and enabling the milk from each cow to be tested, and also to provide improved means for freeing the milk from the vacuum of the plant.

In carrying out the invention the milk is induced to flow from the teats of the cow by means of pulsations produced by causing compressed air to act alternately with the effects of vacuum in teat cups, fitted interna. ly with flexible jaws hinged atthe bottom and normally tending to move outwards or against the casings, said jaws resting on spring supports in the lower ends of the to which constant vacuum connections are also made.

Each jaw has flexibly connected thereto a plunger enclosed in a downwardly inclined cylinder on the outside of the casing", said cylinders being in communication through an air space with a nipple adapted to receive cmnpressed air and vacuum alternately, whereby the plungers are alternately forced downwards and drawn upwards in their cylinders, such downward n'iovements causing the jswsto be forced inwards and down wards in the teat cups in. a manner such-as to give mechanical action on the teats, corresponding closely to the action of the human hand in milking.

The means employed for creating the necessary air pressure and vacuum for operating the machine comprise an air compressor and evhauster operated by a prime. mover in such a manner that at each stroke of its piston air is compressed in one end of its cylinder, while the air on the other sideol said piston is exhausted.

'lhe cylinder is connected from one end and from or near its other end with a vacuum tank, the connections employed being fitted with means whereby pressure is prevented i'rom passing from the cylinder to said tank At one end the aforesaid cylinder is fitted with a smaller cylinder containing a sleeve valve the stem of which projects nor mally into the main cylinder under the influence of a compression spring located between the closed end oi the sleeve valve and the outer end of the smaller cylinder.

The outer end of the latter cylinder is adapted to be put in communication with the pipe line of the system in which air pres sure alternates with vacuum.

From the smaller cylinder at a point just beyond the sleeve valve when the latter occupies its normal position of rest a pipe leads to a compressed air reservoir the latter bein huther pipe with the opposite end of the main cylinder, said last mentioned pipe behip; titted with a nonreturn valve which allows air to enter the reservoir from the cylinder but not to return to the latter.

A pipe leading "from the end of the main cylinder adjacent the smaller cylinder enters the pipe leading from the latter to the compressed air reservoir, while communication is provided. between the outer end of the smaller cylinder and the interior thereof near the main cylinder.

'A valve is provided at the end of the main cylinder adjacent the small cylinder for the purpose of permitting air to pass from the main. cylinder by way oil a pipe which enters the pipe leading; from the smaller cylinder to the compressed air reservoir.

At the inner or closed end of the sleeve valve operating in the smaller cylinder is a smaller spring pressed valve adapted to close against a ring on the inside of said also put in communication through a smaller cylinder. A valve of less diameter than the interior of the smaller cylinder and adapted to open under suction towards the main cylinder is normally held against the other side of the ring in the smaller cylinder by a spring. A connection is also made between the vacuum tank and the smaller cylinder.

The meansfor releasing the milk from the vacuum of the system comprise a chamber in communication with a constant vacuum pipe line, and with an inclined cylinder in which is adapted to be operated by the alternate actions of compressed air and vacuum a hollow piston fitted at its outer or lower end with flap valve. The above mentioned chamber also in communication through a connection with the interior of one or more sets of teat cups, while the outer or lower end of the inclined cylinder is fitted with a weighted flap valve.

Special means are provided for making connections between tubes and pipes without employing rubber connections, and also for supporting the weight of the teat cup claws, thereby enabling the teat cups to hang more securely on the teats.

The invention will however be more particularly described with the aid of the accompanying drawings, wherein Figure l is a sectional elevation of the air compressor, air eXhauster and pulsator.

conne tion between a branch and main pipe.

Referring to Figure l of the drawin 'e 3 is a cylinder within which is reciproc ted by means of a rod 2 actuated from a prime mover a piston 1 said cylinder 3 being closed at both ends and 5.

From at or near its end 5 the cylinder 3 is connected through a pipe 9 with a vacuum tank (net shown) while from its end 4 a pipe 8 a so passes to said tank. The pipes S and re provided with valves 10 and 11 respecti y, whereby air can be exhausted from the tank and parts in communication therewith on the piston 1 moving away from said pipes, and so that pressure will not pass into said pipes 8 and 9 on the reverse strokes of the piston occurring.

At the end 5 of the cylinder 3 is a smaller cylinder 17 in which operates a sleeve valve 18 the stem 19 of which normally projects into the cylinder 3 under the influence ot the compression spring 20 located between the closed end 18 of the sleeve valve 18 and the outer end 1'? of the smaller cylinder 17.

The pipe 21 connects the outer end of the cylinder 1! with the pipe line of the system in which compressed air and vacuum are caused to act alternately.

From the cylinder 17 at a point just beyond the sleeve valve 18 when the latter ocazpies its normal position of rest a pipe 22 ads to a compressed. air storage chamber or *ef-iervoir not shown) the latter also comnunicating with the interior oi the cylinder 3 through its end 4 by means of a pipe 12,

titted with a valve 13 adapted to open under pressure and close under suction.

A pipe 16 con'iniunicating with the interior of the cylinder 3 through the latters end 5 enters the pipe 22 and is litted with a valve 15 which opens under pressure and closes nnder suctioin T he cylinder 17 is provided with a port or mssage one end 01 said port 23 opening into the evlinder 1T nei-it the latters end 17 while the other end of said port or passage 28 opens into the cylinder l7 through the portion thercot near the end 5 ot the cylinder 3.

At the inner or closed end 18 of the sleeve valve 18 is pro--.'i led a sleeve valve 24 connected to and kept normally pressed away from said valve 18 by a spring 25, and adapted to seat itself. against a lived ring 26 inside the cylinder 1?. A valve 21'' surrounding the stem 15.) of the sleeve valve 18 and of less diameter than the interior of the cylinder 1? is norn'ially held against the other side of the ring 26 by a spring 2.

Ports 14; through the cylinder end 5 provide tor con'miunication between the cylinders 3 and 1?.

The piston 1 in moving from the end 4: or the cylinder 3 towards the end 5 thereo'l, creates vacuum in the back end of the cylinder and pre==sure in the front end.

The vacunn'i opens the valve 10 and acts in the pipe 8 connected with the vacuum tank thereby exhausting air from the latter and parts in communication therewith, said vacuum at the same time closing the valve 13 in the pipe 12 connnunicating with the compressed air reservoir.

The pressure created on the other side of the piston 1- closcs the valve 11 and opens the valve 15, whereby said pressure is enabled to pass into the pipes 16 and 22 con- 23 open at both ends to its interior nected with the compressed air reservoir and to pass with pressure from the latter into the cylinder 17 beyond the sleeve valve 18 and ultimately through the pipe 21 to the pulsating. line of the system.

At the same time, air pressure passing through the ports 14c forces the valve 27 hard against the ring 26.

Continuing the same stroke the piston 1 strikes the stem 19 of the valve 18 and me ves the latter in the cylinder 17 against its spring 20towards the end 1'? thereof until it closes the end of the pipe 22 opening into said cylinder 1?. Shortly following the closing of the pipe 22 by the valve 18 and after the sprin 25 has expanded the valve 2 1 is drawn from opposite the pipe 23, which is in communication with the vacuum tank, thereby permitting vacuum to act in pipe 21 via pipe 28 and port 28.

l Vith the air pressure unable to enter the cylinder 17 from the pipe 22 it all passes to the compressed air reservoir via the pipes 16 and 22.

l i hen the sleeve valve 18 is at the limit of its outward stroke, the piston 1 is close to the end 5 of the main cylinder 3, and is past the pipe 9 leading to the vacuum tank.

U11 the piston 1 commencing its return stroke the sleeve valves 18 and 24% also commence to move in the reverse direction under the expansion of the spring 20.

The return stroke of the piston 1 creates vacuum in the end of the cylinder 3 connected with the cylinder 17 and pressure in the opposite end, said pressure opening the valve 13 and passing via the pipe 12 to the compressed air reservoir and also having the effect of closing the valve 10.

The vacuum created in the end of the cylinder 3 in communication with the cylinder 1? acts through the ports 14 and pulls the valve 2'? surrounding the stem 19 away from the ring 26 against the action of its spring 29 thereby permitting the vacuum to act through the passage of port 23 inconjunction with the vacuum from the pipe 23 and to act in the outer end of the cylinder 17 so as to exhaust air in the pipe 21 and parts in communication therewith.

During this movement the sleeve valve 18 prevents communication between the cylinder 17 and the compressed air reservoir by covering the end of the pipe 22, opening into saidcylinder. i

The movement of the sleeve valves 18 and 24- together in the cylinder 17 continues until the valve 24 seats itself against the ring 26 and closes the opening or passage through the same, at. the same time as or shortly following the closing of the end of the pipe 23*.

The latter action completely cuts off the vacuum from the port or passage 23. The

valve 24 is now stationary while the valve 18 is still moving under the influenceof the spring 20 which is stronger than the spring 25.

The valve 18 continues to move away from the end 17 until it reopens the pipe 22 to the cylinder 17, whereupon it comes to rest.

The movement of the valve 18 while the valve 24 is at a standstill results in the spring 25 being compressed, such compression being required in order that said spring 25 will cause the valve 2a to keep the end of the pipe 23 covered until such time as the pipe 22 is cut off from the cylinder 17 by the valve 18, when the latter is being forced by the piston 1 towards the end 17.

The result of the opening of the pipe 22 by the sleeve valve 18 is that the vacuum acting in the pipe 21 and parts in communication therewith is broken down by pressure being again admitted into the outer end of the cylinder 17 through the'pipe 22, such pressure being prevented from passing any where else.

The piston 1 continuing its stroke towards the end a of the cylinder 3 passes the pipe 9 immediately following which the valve 11.

opens under suction allowing air to be eX- hausted from the vacuum tank and parts in communication therewith, such action continuing until piston 1 completes its stroke.

The constant vacuum pipe line 45 Figure 2 is in communication with the vacuum tank from and through which air is ex:- hausted by the movements of the piston 1 within the cylinder 3.

The vacuum and compressed air pressure pipeline an Figure 2 is in communication with the pipe 21 from the end 17 of the cylinder 17. i

The milk releasing means Figure 2 comprises a chamber 41 having a reduced lower end communicating through a port a2 with the larger portion of a two diameter inclined cylinder 28 having at its lower end a flap valve 29 provided with a weight 30 which causes said valve to normally close the lower end of said cylinder 28.

The upper end of the cylinder 28 has screwed thereon a cap 16 formed with a tubular portion 46 adapted to be inserted in the pipe line 17 so as to form part thereof, whereby the alternate air pressure and vacuum acting in said pipe line will also act in the upper end of the cylinder 28 and in the connection 418 which is in communication with pulsation s aaces of teat cups.

The top 43 of the chamber 41 fits inside the latter and is provided with a tubular portion 4:3 which communicates with the interior of the chamber 41 through a port 15, and is inserted in the main milk and vacuum pipe line 45 in order that the vacuum III acting in the latter will also act in the chamber 41, and the connection a l in communication with the interior or milk spaces of teat cups. The connection 446 is formed with a hollow spherical end 44 which is retained in a concave seating 6 in the top 13 by a spring clip 7 secured to the tubular portion 43 and shaped to lit over the spherical end 4:4 which is open to the connection i l and contains a port 6 registering with a port 7 through the top 43.

A hollow piston 31 fitted with a flap valve 40 at its open or lower end and containing ports 39 in its closed end works in the larger end of the cylinder 28 and is secured to one end of a rod 32 passing through a stu'lting box 38 in the wall 38 between the smaller and larger diameters of the cylinders, into the smaller portion of the cylinder 28. A plunger is detachably connected to the other end of the rod 32 by a pin 26 which also enters guide slots 26" in the cylinder 28.

A spring 37 surrounds the rod 32 between the plunger and the wall 38.

ln operation the pulsations caused by the alternate action of compressed and vacuum in the pipe line 47 are transmitted to the teat cups in communication with the connection 18 and also act in the upper end of the cylinder 28.

The constant vacuum acting in the pipe line L and through the chamber ll draws milk from the teat cups in communication with the connection eel into the chamber at said milk falling by gravity in the latter and passing through the ports 39 in the piston 31 to accumulate in. the lower end of the cylinder 28 which is closed by he weighted valve 29 assisted by the action of vacuum in said cylinder.

When air pressure from the pipe line a? is admitted to the upper end of the cylinder 28 the plunger is forced downwards in the upper or smaller portion thereof against the action of the spring 37. This downward movement of the plunger 33 also forces the piston 31 downwards against the milk accumulated in the lower end of the cylinder 28, whereby the flap valve is closed and the milk compressed until the flap valve 29 is forced open and allows the milk to escape to atmosphere.

\Vhen vacuum from the pipe line 4? acts in. the upper end of the cylinder 28 the plunger 33 assisted by the spring 37 moves upwards drawing with it the hollow piston 81. On upward movement of the latter occurring the weighted valve 29 closes by gravity and assisted by the vacuum created by the movement of the piston 31 again seals the lower end of the cylinder 28. Milk has, during the time the flap valve 40 has been closed, been accumulating in the piston 31, and as soon as the valve 29 closes and (ill the pressures on each side of the valve ll) become more or less equal, the weight of milk forces the valve 4L0 to open and allow the milk to again accumulate in the lower end of the cylinder 28.

The pin 26 is entered in the guide slots 26 for the purpose of preventing the piston 31 from turning in the cylinder 28 so that the hinge of the valve 10 will be retained uppermost.

The milk on being released from the cytinders 28 passes into a chute which leads it to where required.

The milk releasing means illustrated in Figure 2 can be fitted in each cow bail in order to release the milk from each cow apart from the milk from the other cows, so that the amount of mill: taken from each cow and the quality of same can be observed and ascertained. lVhen this is done, the milk released from the cylinder 28 passes into a receptacle 51 fitted in the chute 50, said receptacle being provided with a s ale or series of markings 51 for measuring the milk and also with an outlet controlled by a cock 52 for allowing the milk to pass into the chute 50 when finished with.

On the other hand one releasing apparatus can be employed for the whole plant if desired.

The teat cups are each constructed as shown in Figures 5 to 10.

Each teat cup comprises a casing having a closed convex lower end 100 with a port 103 through same, and an enlarged upper end in which screws a flanged mouthpiece 93 the lower portion 94 of which has an internal diameter equal to the internal diameter of the body of the casing and adapted to be seated on a seating 95 at the junction of the smaller and enlarged portions of the casing 70.

The mouthpiece 93 is shaped so that when inserted in the enlarged upper end of the casing, an annular space 87 is left between the casing and said mouthpiece v the latter also having an internal horizontal ring 96 with an upturned and tapered inner edge 96 A ring 98 screwing into the mouthpiece 93 is provided for the purpose of pinching and holding a short piece of rubber tubing 97 against the upturned edge 9G" so that said tubing 97 is secured vertically as shown in the drawing. The provision of the rubber tubing 97 in the teat entrance to the cup enables the cup to cling to the teat and to secure a firm hold thereon.

In the casing 70 are provided a number of upright hinged jaws each secured to the upper ring 81 of a spring 82 resting on the bottom 100 of said casing.

Each jaw consists preferably of a light wire frame 80 having attached thereto a 7 means sheathing of flexible material 80. the frames 80 is formed integral with the spring 82, while the other frames are formed outsides of the latter as shown at 80 in the drawing.

Instead of reinforcing; the flexible material 80 oi the jaws with the stifi'eningr material 80" single pieces of material thickened or stiifened at the stop portion so as to be rigid, and thin enough to be flexible or pliable at the lower portion can be secured to the frames, 80.

The jaws are formed and titted to the upper ring 81 of the spring 82'so as to naturally tend to open or press outwards against the casing 70. j

A hollow plunger 85 in each cylinder 84 is flexibly connected to a jaw preferably by having at its lower tapered end a projection 91 with a knob 92 on the end, the neck of said projection being entered in a downturned claw 86 on the outside of the lower end of the stiffening piece 80 101 the stiffened portion of the jaw. A nipple 88 opening chamber 87 is adapted to be put in communication with the pulsation line 47 of the system through the connection 48.

A hollow sphere 101 on the endxof a connection 102 in communication with the milk chamber of a claw 61 has a port 10d which registers with the port 103 in the lower end the milk chamber of the claw 61'.

100 of the teat cup casing and is retained in said end 100 by a spring clip 105 secured to said casing.

The connection as Figure 2 is in communication with the pipe 62 Figure 3 which in turn is open to the milk chamber of the claw 61. The connection between the'claw 61 and pipe 62 is made by means of a hollow downwards against the teat, thereby obtaining a squeeze similar to that given by the One of into the annular.

human hand in milking. This action combined with the etl'ect oi vacuum acting constantly in the interior of .the cup through the lower connection 102 results in the milk being induced from the teat and to pass into the connection or pipe 102 from which it ultimately finds its way to releasing apparatus.

lVhcn the supply of compressed air is cut off from the cylinders at and vacuum caused to act therein the plunge-rs 85 move upwards and the jaws assisted by the spring 82 move upwards and open outwards.

The flexible jaws are stitlened at their upper portions sothat when ttorced inwards by the plungers 85, said stiffened portions grip or obtain a firm hold around the upper portion or root oi the teat before the lower flexible portions commence to squeeze or grip the lower portion thereof.

Byregulating the gripping of the teat by the jaws as described and at the same time causing the latter to give a downwardly moving orsliding grip or squeeze, the milk isindu'ced to flow much more freely from the teat than where. a more or less uniform or even horizontal squeeze is given. thereby enabling cows to be completely milked and avoiding hand stripping.

Provision is made for supporting or tale ing the weight of the claws 61 by providing the latter with lugs 74 (Figures 3 and ll each of which contains an opening 76 into which a suspending wire or the like 72 is pinched by 'thumbscrews 7 5' working through said lugs.

The wires or the like 72 contain tension springs 77 for the purpose of making; the wires elastic. The means for connecting a branch line 53 with a main or other line 54 (see Figure 11) comprise hollow spheres 55 and 57 the former being secured in and having communication with the line 54 through directly opposite ports 56. while the latter sphere is attached to the end of the line 53 shaped to embrace. and hold the sphere 57 or vice versa.
